Specifically, with reference to fig. 2 to 5 and fig. 8, in order to improve the stability and reliability of the sliding movement of the second backrest 30a relative to the first backrest 20, the first backrest 20 is provided with a height guide rail 21, and the second backrest 30a is provided with a matching guide structure 31 in sliding fit with the height guide rail 21; preferably, the height guide rails 21 and the guide mating structures 31 are each disposed in a side-to-side arrangement on the child safety seat 10 to increase the reliability of the sliding connection between the second backrest 30a and the first backrest 20; for example, the height guiding rail 21 is a linear slot, and the guiding structure 31 is a pin inserted into the linear slot, but not limited thereto. It can be understood that, according to actual needs, the height guiding rail 21 can be set on the second backrest 30a, and correspondingly, the matching guiding structure 31 is set on the first backrest 20, so that the purpose of guiding the height guiding rail 21 and the matching guiding structure 31 to each other can be achieved. More specifically, the following:
as shown in fig. 4 to 9, the lateral wing 40 is embedded in the adjusting body 30, so that the lateral wing 40 is limited in the adjusting body 30 in the front-rear direction of the child safety seat 100, and the adjusting body 30 blocks the lateral wing 40 from shaking in the front-rear direction of the child safety seat 100; the adjusting body 30 is embedded in the first backrest 20, so that the adjusting body 30 is limited in the first backrest 20 in the front-rear direction of the child safety seat 100; the second backrest 30a is opened with an escape space 32 through which a second guide 54 described below passes, and provides an escape position for the second guide 54 to slidably move on a second guide rail 52 described below. Specifically, as shown in fig. 4, 6 and 7, in the adjusting body 30, the second backrest 30a and the headrest 30b are arranged side by side in tandem, and the shoulder 40 is located between the second backrest 30a and the headrest 30b in the front-rear direction of the child safety seat 100, so that the assembly operation of the second backrest 30a, the headrest 30b and the shoulder 40 is facilitated, but not limited thereto.
As shown in fig. 4, 5, 7, 8 and 9, the wing height and width synchronization adjustment mechanism 50 includes a first rail 51 extending in the width direction (i.e., indicated by arrow B) of the child safety seat 100, a second rail 52 extending in the height direction of the child safety seat 100, a first guide 53 slidably engaged with the first rail 51, and a second guide 54 slidably engaged with the second rail 52. The first guide rail 51 is disposed on the side wing 40, the first guiding component 53 is disposed on the adjusting body 30 (specifically, disposed on the second backrest 30a of the adjusting body 30), of course, the first guiding component 53 may be disposed on the side wing 30 according to actual requirements, and correspondingly, the first guide rail 51 is disposed on the adjusting body 30, so the invention is not limited thereto; the second guide rail 52 is provided on the side flap 40, and the second guide 54 is provided on the first backrest 20, but the second guide 54 may be provided on the side flap 40 as needed, and the second guide rail 52 is provided on the first backrest 20, accordingly, the present invention is not limited thereto. In the process of adjusting the height of the headrest 30b, the headrest 30b simultaneously slides on the first guide rail 51 by the first guiding member 53 and slides on the second guide rail 52 by the second guiding member 54 to link the lateral wings 40 to synchronously adjust the height and the width, so that the adjusted states of the lateral wings 40 and the headrest 30b are shown in fig. 3 and 4, and the states of the lateral wings 40 and the headrest 30b when not adjusted are shown in fig. 1 and 2. Specifically, the wing 40 performs outward expansion or inward contraction translation and rotation relative to the first backrest 20 under the sliding action of the first guiding element 53 along the first guiding rail 51 and the sliding action of the second guiding element 54 along the second guiding rail 52, so that the height and width of the wing 40 can be adjusted more smoothly, and the occupied moving space during the adjustment process is smaller. For example, the first guide rail 51 is a first curved slot, the first guiding element 53 is inserted into the first curved slot and slides in the first curved slot along the extending direction of the first curved slot, preferably, the first curved slot is an arc slot protruding upwards, and the first guiding element 53 is a pin; meanwhile, the second guide rail 52 is a second curved slot, the second guiding element 54 is inserted into the second curved slot and slides in the second curved slot along the extending direction of the second curved slot, preferably, the second curved slot is an arc-shaped slot gradually expanding outward from bottom to top, and the second guiding element 54 is a pin shaft element, so that the outward opening or inward contraction translation and rotation of the side wing 40 relative to the first backrest 20 are smoother under the actions of the first guiding element 53 sliding along the first guide rail 51 and the second guiding element 54 sliding along the second guide rail 52, but not limited thereto. In order to make the lateral wings 40 have a tendency to expand outward in a normal state, for example, in fig. 7, 9 and 10, the lateral wing height and width synchronous adjusting mechanism 50 further includes a lateral wing restoring member 55 that constantly drives the lateral wings 40 to expand outward relative to the first backrest 20, and the lateral wing restoring member 55 is disposed between the lateral wings 40 and the adjusting body 30; specifically, the lateral wing restoring member 55 is an elastic member, such as the torsion spring illustrated in fig. 7, 9 and 10, of course, the lateral wing restoring member 55 is selected to be a compression spring or an extension spring according to actual needs, as long as it is ensured that the assembling position of the lateral wing restoring member 55 always has the function of urging the lateral wing 40 to open outwards relative to the first backrest 20; of course, the wing-restoring member 55 can have a tendency to urge the wing 40 to contract inwardly relative to the first backrest 20 according to actual needs. It will be appreciated that the wing return 55 may be a torsion, compression or extension spring, regardless of whether the wing return 55 has a constant tendency to urge the wings 40 to expand outwardly relative to the first backrest 20 or to contract inwardly; of course, according to the actual requirement, the wing resetting member 55 may further include a first magnetic structure and a second magnetic structure, wherein the first magnetic structure is installed on the wing 40, and the second magnetic structure is installed on the adjusting body 30, preferably the headrest 30b of the adjusting body 30, so as to achieve the capability of expanding outwards or contracting inwards by means of the attraction or repulsion of the magnetic force, but not limited to the above examples.
As shown in fig. 6 and fig. 8 to 11, the flank height and width synchronization adjustment mechanism 50 further includes a lock release operation member 56 and a lock element 57 linked with the lock release operation member 56. The locking member 57 is movably assembled to the adjusting body 30, preferably, the locking member 57 is slidably installed on the second backrest 30a of the adjusting body 30 along the front-rear direction of the child safety seat 100, and the first backrest 20 is provided with sixteen step locking portions 221 spaced apart from each other along the height direction of the child safety seat 100, and of course, the step locking portions 221 are provided as two, three, four, five or six different ones according to actual requirements, so the invention is not limited thereto. The locking element 57 locks the height adjustment of the adjustment body 30 relative to the first backrest 20 when locking 221 is performed with any one of the segment locking parts, i.e. blocks the height adjustment of the adjustment body 30 relative to the first backrest 20; the adjusting body 30 can be height-adjusted with respect to the first backrest 20 when the locking part 57 is unlocked from the step engaging part 221 to allow height adjustment of the adjusting body 30 with respect to the first backrest 20 to prevent accidental play of the adjusted headrest 30b by the engagement of the locking part 57 and the step engaging part 221. Specifically, for example, in fig. 7 to 9, in order to realize the operation of separating the locking element 57 from the distance, the wing height and width synchronization adjustment mechanism 50 further includes an intermediate linkage 58, the intermediate linkage 58 is disposed between the lock release operation element 56 and the locking element 57, so that the lock release operation element 56 is linked with the locking element 57 through the intermediate linkage 58 to be separated from the locking with the segment locking portion 221, preferably, the locking element 57 extends along the width direction of the child safety seat 100, the intermediate linkage 58 extends along the height direction of the child safety seat 100, and the locking element 57 is linked with the intermediate linkage 58 to slide along the front-back direction (i.e., indicated by the arrow C) of the child safety seat 100, so that the locking or unlocking between the locking element 57 and the segment locking portion 221 is easier. More specifically, for example, in fig. 10, the middle interlocking member 58 has a tilting structure 581 that is tilted forward and backward with respect to the height direction of the child safety seat 100, and the middle interlocking member 58 moves the locking member 57 forward and backward away from the locking with the segment locking portion 221 through the tilting structure 581 during sliding along the height direction of the child safety seat 100, so that the locking member 57 and the segment locking portion 221 are released more reliably. In order to ensure that the middle linking member 58 and the locking member 57 are linked more reliably, for example, in fig. 10, the middle linking member 58 is provided with a driving inclined slot 58a which is long and inclined forward and backward with respect to the height direction of the child safety seat 100, the driving inclined slot 58a penetrates through the left and right sides of the middle linking member 58, the locking member 57 penetrates through the driving inclined slot 58a and can slide on the driving inclined slot 58a, and the inclined structure 581 is formed on the upper side groove wall and/or the lower side groove wall of the driving inclined slot 58 a.
As shown in fig. 11, in order to ensure that the locking element 57 is locked with the first backrest 20 more reliably, the first backrest 20 where the segment locking portion 221 is located protrudes outward to form a protruding strip 22 extending along the height direction of the child safety seat 100, the segment locking portion 221 is formed on the protruding strip 22, and correspondingly, the intermediate linking member 58 is provided with an avoiding space 582 extending along the height direction of the child safety seat 100, and the protruding strip 22 is located in the avoiding space 582; for example, the locking element 57 is a rod or a pin, and the segment locking portion 221 is a slot structure, but not limited thereto. It can be understood that when the segment locking portion 221 is disposed by the second backrest 30a of the adjusting body 30, the protruding strip 22 is disposed by the second backrest 30 a.
